+From: Johannes Berg <johannes.berg@intel.com>
+Subject: [PATCH] mac80211: make LED trigger names available early
+
+The throughput trigger will require doing LED
+classdev/trigger handling before register_hw(),
+so drivers should have access to the trigger
+names before it. If trigger registration fails,
+this will still make the trigger name available,
+but that's not a big problem since the default
+trigger will the simply not be found.
